They can't let you go.
Not now, not ever- you- You've seen every part of them, every impulse they've held down since their presentation, you know more about them than anyone else, they aren't going to let you go now! You two had lived together for two years! They know you just as well, why the hell do you want to let them go?
They're being irrational, cognitively, Orion knows this as they tie down the windows of your shared bedroom from the outside, glancing in at you on the inside. You're laying there, legs and arms tied together, and they hate just how pathetic you look right now. How sad. They're being irrational- possessive, obsessive, in-fucking-sane. But they can't bring themself to care, they love you way too fucking much to let you go. They heard those words come from your mouth, those dangerous fucking words, and they couldn't handle it.
They'll apologize to you later. They'll fix everything, and you'll be in their arms, and they'll apologize and you'll love them again. Fuck anyone else. Especially that little brat who convinced you- no, no, they can't… they can't go too far. They can't think about that little brat who tried to tell you they were just a wolf in sheep's clothing. That no alpha could be trusted, let alone the ones that try to play house. That brat can be dealt with later. They just need to convince you to hold them again. To love them again.
Their breath is heavy as they finish tying the windows down, turning to head into the house again. It's time they start cooking you dinner.
“Sweetheart, what would you like for dinner tonight?”
